When streamoff is called on the context and the context

2] sometimes v4l2_m2m_job_finish may not succeed as the m2m_dev->curr_ctx

The above points may stop the execution of the other queued contexts.

that context should "not be running" or "not queued" in the job_queue.
1] If the current context is running, then abort job will be called.
2] If the current context is queued, then the context will be removed from
the job_queue.

this is a new gspca driver for Syntek STK1135 webcams. The code is completely
new, but register values are based on Syntekdriver (stk11xx) by Nicolas VIVIEN
(http://syntekdriver.sourceforge.net).
Only one webcam type is supported now - vendor 0x174f, device 0x6a31.
It's Asus F5RL laptop flippable webcam with MT9M112.
The camera works better than in Windows - initializes much faster and
provides more resolutions (the sensor can do almost any resolution - just
add it to the stk1135_modes[] - could this feature be somehow used by
applications to avoid SW scaling?).
Autoflip works too - when the camera is flipped around, the image is flipped

[media] exynos-gsc: fix s2r functionality
When gsc is in runtime suspended state, there is no need to call
m2m_suspend during suspend and similarly, there is no need to call
m2m_resume during resume if already in runtime suspended state. This
patch adds the necessary conditions to achieve this.
